The movement of a gene from one linkage group to an other is called

Options

A. Crossing over
B. Inversion
C. Duplication
D. Translocation

Answer

To answer the question "The movement of a gene from one linkage group to another is called," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Terms**:
- We need to define and understand the terms related to genetic movements: crossing over, inversion, duplication, and translocation.

2. **Define Crossing Over**:
- Crossing over is the exchange of genetic material between homologous chromosomes during meiosis. It results in genetic recombination but does not involve the movement of genes between different linkage groups.

3. **Define Inversion**:
- Inversion is a chromosomal rearrangement where a segment of a chromosome is reversed end-to-end. This process occurs within a single chromosome and does not involve movement between linkage groups.

4. **Define Duplication**:
- Duplication refers to the process where a segment of a chromosome is copied, resulting in multiple copies of that segment. This also occurs within a single chromosome and does not involve movement between linkage groups.

5. **Define Translocation**:
- Translocation is the movement of a gene or a segment of a chromosome from one linkage group to another. This can occur due to chromosomal abnormalities and is the correct answer to the question.

6. **Conclusion**:
- Based on the definitions, the movement of a gene from one linkage group to another is specifically called **translocation**.

### Final Answer:
The movement of a gene from one linkage group to another is called **translocation**.
